Field Concrete Testing San Diego

What it is: Testing freshly mixed concrete at construction sites is required per code which includes sampling the concrete from the truck. This field testing procedure checks for temperature, slump, and we cast a set of cylinders for compressive strength verification.

What it does: Slump is a field test to measure water quantity which is mixed within the sand, rock and cement. This is mainly for field-use measurement as a guide for the work-ability of concrete. The concrete temperature is checked and compared to a specified degree range as stated in the ACI 318 code book. Casting a set of freshly mixed concrete cylinders for compressive strength testing. This testing procedure is required to be reported to the design engineer. The compressive strength test results (psi) pounds per square inch are verified per design engineer plan requirements. This can range from 3000 to 8000 psi depending on the structural location and application.

What we do: In the field, we test the freshly mixed concrete for temperature, slump and cylinder samples for compressive strength.

Concrete is tested in the plastic state for slump, air content and unit weight. In addition, test cylinders and beams can be cast to determine compressive and flexural strength.

Reinforcing Steel Inspection

Re-bar are steel bars of various diameters and lengths which have steel ribs that add to the bonding value of concrete for adhesion and additional strength. Reinforcing steel and concrete are bonded together by a mechanical connection.This provides the tensile properties which adds another element of strength to the concrete.


Field Concrete Testing

The testing of concrete at the construction site is to sample the freshly mixed concrete, check for slump, temperature and cast a set of cylinders for compressive strength verification. Slump is a field test to measure water quantity mixed within the concrete. This is mainly for field-use measurement as a guide for the work-ability of concrete.


Post-Tension Concrete

Post-tension concrete cables are long steel cable ropes, usually 1/2″ in diameter within a plastic protective grease coated sheathing. Post-tension concrete cables are a group of cable tendons placed within the concrete providing compression strength laterally. Post-tension concrete cables which are placed within the concrete allows the concrete to be elevated as it has compressive lateral strength.


Field Testing

We perform almost any type of inspection services. Our clients enjoy the quality of our field inspections and structural inspections. Prestressed/Post-Tensioned Concrete, Shotcrete, Structural Masonry, Structural Steel Erection & High Strength Bolting, Structural Steel Visual Welding Inspection, Structural Steel Non-Destructive Evaluation, Spray Applied Fire-Resistive Materials, Lateral Framing (Wood & Cold-Form Steel Structures)


Welding Inspection

Steel is the structural soundness and integrity of the building. If welding is not done by code or procedure it could result in defective work which would lead to the removal of weld areas by grinding and re-welding. As Certified Welding Inspectors Metzger Testing & Inspection can provide guidance to the contractor in producing a welding procedure specification…


Materials Testing

The best field inspection personnel cannot be efficient without excellent support from the laboratory. Metzger Testing & Inspection works with the top laboratory material testing facilities in the area that have quality testing and diagnostic equipment. Concrete and masonry samples, soil, asphalt, fire resistive materials, and many other material types are tested in-house.
